1 Fuji Electric Instrumentation & Control A New Generation of Transmitters ECNO : 610d

2 A New addition to the FCX Family at the edge of Technology As a leader in the field of pressure measurement, Fuji Electric has an installed base of more than 750,000 FCX transmitters all around the world. Using leading edge technology in silicon chip manufacturing, FCX transmitters incorporate a high performance micro capacitance silicon sensor. This sensor is machined into the silicon to create the unique floating design which gives the transmitters robustness and an unbeatable accuracy specification. In response to customer demand Fuji Electric has developed two variations of the transmitter. Firstly, the FCX AII series which is a high performance transmitter, designed to solve the toughest of applications where special materials and design is needed. Secondly the FCX CII series which is a high accuracy transmitter designed as an economic solution to most applications. The combination of FCX AII/CII transmitters allows us to offer a variety of measuring ranges built and configured to meet individual application requirements in most industrial markets. -CII -AII 2 Our facility at Fuji Electric France SA was formed in 1995 and within 18 months was accredited with ISO quality certification - AFAC in November The last update of the ISO 9001 : 2000 standard was successfully completed in October 2003 and provides quality assurance for our sales and manufacturing activities. Approvals SIL - PED NAMUR- NACE GOST - ATEX FM - CSA - JIS

3 Fieldbus (FF) FOUNDATION Protocoles TM Hart /Fuji (bilingues) - AII series PROFIBUS All FCX AII & CII are transmitters are Smart and provide 4 to 20 ma & superposed digital signals. The transmitters use bilingual language capability which uniquely provide Hart and Fuji protocol as standard. In addition FCX AII & CII can be supplied to communicate using either Foundation Fieldbus H1 or Profibus PA protocols. The Fuji Electric hand held communicator (HHC) is a very useful configuration tool for FCX AII/CII series transmitters. As a menu driven device the HHC can be used to remotely display and configure transmitter parameters: Principle programmable parameters : Zero Type of output signal (linear or square root) Span Damping Burnout Current generation Output signal Tag Auto diagnostic Model number of the transmitter Liquid crystal display using 4 lines and 16 characters Intrinsically safe Printer as an option Using the HartTM communication protocol the FCXAII/CII transmitters can also be configured by any Hart protocol compatible hand held. FCX AII/CII series pressure transmitter can also be configured using Hart TM communication based software connected to your Laptop or PC. Configuration of the above parameters is possible and the settings can also be saved for future reference. It is also possible to measure and record process values. The interface between the PC and the transmitter is performed by a mini modem USB/Hart to guarantee the communication between the PC and the 4 to 20 ma loop of the transmitter. 3

4 Silicon sensor, a micro capacitance based technology Accuracy: +/- 0.07% Of calibrated span (FCX AII) Based on our extensive silicon chip manufacturing experience, Fuji Electric developed the unique micro capacitance silicon sensor as the centrepiece of FCX AII/CII transmitters. The silicon sensor is mounted floating in the measuring cell neck to minimize the static pressure and temperature effect (4.5 times better than a conventional sensor) which provides an improved signal to noise ratio. As a measuring diaphragm material, the sensor uses a single crystal silicon that has minimal hysteresis and fatigue which improves the transmitter s characteristics improving long term stability and reliability. FCX transmitters FCXAII/CII comply with manufacturing quality control according the ISO 9001 requirements. Long term stability: +/- 0.1% Of max. span/3years Micro-capacitante silicon sensor Measuring cell Process flanges (same for all models up to 100 bars) ASIC Technology In developing the series FCXAII/CII we used large scale integration (LSI) in a new ASIC, which contains both digital and analogue circuits. This further improves performance and reliability. Sensor Unit Electronics Unit ASIC based electronics EEPROM Temperatur Sensor Communication Modem Full interchangeability Optional indicator (Analog or LCD) Temperature Sensor Analog to digital converter EEPROM Micro Processor Digital to Analog Converter As individual configuration data of both, electronic unit (amplifier) and measuring cell, are stored separately in its own EEPROM, the interchangeability is guaranteed over the entire range of FCX transmitters series FCXAII/CII models including differential pressure, pressure, absolute pressure, level and remote seal transmitters. This allows a minimum stock of spare parts for maintenance. Microcapacitante Silicon Sensor HHC 4-20mA Signal 4

5 Many additional configurations Programmable output signal The FCXAII/CII s output can be configured to provide linear or square root output. In addition the output signal can configured using a 15 point linearization table to provide a non-linear output to suit specific applications, like the liquid volume measurements or non- symmetrical tanks or specific shapes Linear output signal Square root output signal Customized output signal Application Example Volume measurement of laid cylinder tank Burnout current In conformance with the recommendations of NAMUR NE 43 the output of the transmitter can be driven to a specific value should the transmitter experience an internal failure. The standard output signal limits are 3.8 to 20.8 ma and in case of a transmitter failure, the burnout direction can be either up or downscale being programmable between 20.8 and 21.6 and between 3.2 and 3.8 ma. Digital Indicator The FCXAII/CII models can be fitted with an optional local analogue, or digital indicator. The digital indicator is based on LCD technology and shows the information on 2 lines each of 6 digits and also includes 3 switches. The indicator can be used to show the output signal in engineering units, as a percentage or as a current in ma (this is useful for flow indication on a differential pressure transmitter). The type of measurement, the output signal and the value are shown on the screen (%, ZERO, DISP, OUT, FIX,, ABS, -, Facteur d échelle). Three switches on the indicator allow the configuration and selection of adjustments: LOCAL/COMM : choice for local or remote adjustment DAMP : local adjustment of the damping MODE : Selection of Zero, Span and loop calibration local adjustment via the screw on the outside of the electronics housing Under scale burnout Probable under range MODE switch DAMP switch Digital display of process values Engineering unit LOCAL/COMM switch Normal operating range Probable over range Over scale Burnout Easy Installation The LCD indicator can be fitted in any one of 4 positions allowing it to be rotated 360 (90 steps). In addition the electronics housing can be rotated +/- 180 to suit all mounting positions and installations. 5
